Question 1

Perez-Nogues Vet Sx 2018 PQ

Evaluation of the effects of initial water temperature & curing time on fiberglass cast strength

• what produced strongest cast?
• recommendation?
• PQ optimal water temperature for fiberglass strength

Answer 1

42°C (warm)*

Strongest casts were produced with warm water & after curing for 24 hours*

Use of warm water * is recommended to initiate fiberglass cast curing, especially if the casted limb will be loaded soon after cast application

Question 2

Caraty JSAP 2019

Comparison of the different supports used in veterinary medicine for pressure sore prevention

• risk zones?
• which method best?
• impact of BCS?

Answer 2

Regardless of BCS & support used, skin overlying scapula-humeral articulation, the greater trochanter & thirteenth rib were recurrent risk zones

In these risk zones – pressure-relieving mats led to lower pressures than standard mats or blanket placed on the floor

The contact pressures appeared to depend on BCS, with maximal pressures observed in thin dogs

Question 3

Schlag JAVMA 2019 PQ

Analysis of outcomes following treatment of craniodorsal hip luxation with closed reduction and Ehmer sling application in dogs

• % reluxation? Effect of Trauma? PQ
• % ST injuries?
• 3 things that increased odds of ST injury and odds ratio?

Answer 3

40/92 (43%) dogs had reluxation of affected hip joint at or near the time of sling removal. ***
** 5x more likely to reluxate if initial injury due to trauma. **

46 (50%) dogs had soft tissue injuries secondary to sling use; 17 of these dogs had injuries classified as severe, including 1 dog that required limb amputation

Odds of severe sling injury
- poor owner compliance 12x
- sling placed by an intern rather than board-certified surgeon or resident 4x
- noted to have soiled or wet bandage on > 1 occasion ~6x
